The article presents the results of neutronic calculations for the BN‑600 and BN‑800 reactors using the new BNAB‑RF22 group constant library. The aim of the study is to ensure consistency between evaluated nuclear data and group constants for supporting the BN‑600 and BN‑800 reactors with high‑precision and diffusion codes. To achieve this goal, it is necessary to select an evaluated nuclear data library that is best suited for supporting the BN‑600 and BN‑800 reactors. To this end, benchmark experiment calculations and test models integrated into the ISIDA software package were performed. The scientific novelty of the work lies in addressing the consistency of constant libraries used in engineering and high‑precision code calculations for the BN‑600 and BN‑800 reactors through the development of the BNAB‑RF22 library. The practical significance of the research consists in the development and verification of the BNAB‑RF22 group constant library for calculating the neutronic characteristics of the core regions of the BN‑600 and BN‑800 reactors. The study employs modern methods of neutronic calculations, including high‑precision codes MCNP and MMK.
